ASACOM™ ASA Plastic
ASACOM™ is our trade name for Acrylonitrile Styrene Acrylate (ASA) compounds which we can offer with a range of properties and colours. ASA products are characterised by excellent resistance to weathering, both in terms of mechanical properties and colours. As such, our ASA polymer grades are widely used for leisure and outdoors applications as well as in the automotive industry. Our ASA polymer grades additionally offer exceptional weatherable properties including gloss and colour retention.
If you require something tougher that still retains the exceptional weathering performance of our ASACOM™ product range, then our PC-ASACOM™ grade S9470 will be an excellent fit for your application. Combining Acrylonitrile Styrene Acrylate properties with the strength benefits of polycarbonate.
What is ASA plastic?
Acrylonitrile Styrene Acrylate (ASA plastic) is very similar to Acrylonitrile, Butadiene and Styrene (ABS plastic). ASA plastic is made of tiny acrylate rubber particles crosslinked and chemically attached to styrene-acrylonitrile copolymer chains. These particles are then embedded in a styrene-acrylonitrile matrix.
Weathering resistance is the most significant difference between ABS plastic and ASA plastic. ABS plastic cannot withstand prolonged outdoor exposure due to Ultra Violet content within sunlight attacking the butadiene rubber component of the ABS polymer matrix. Over time, this will cause ABS to become ‘brittle.’
Key Benefits of ASA Polymer
• Superior outdoor weatherability
• Retains gloss, colour, and mechanical properties post-outdoor exposure.
• Higher temperature resistance than ABS polymer.
• Superior water resistance.
• Will not “yellow” with the passage of time.
Here are our main grades. Clicking on a specific grade name will give you access to a summary of the datasheet. If you require a full datasheet, with more test results and details on the processing recommendations, please go here. If the datasheets for the polymer compounds you’re looking for are not on there, please contact us directly at Polymer Compounders and one of the team will be more than happy to assist you. Each datasheet has been composed by a company working to an ISO9001:2015 standard and should not be taken to be approved or sanctioned by the auditor to this standard.
